Summary: A dialect continuum from Siha to Usseri. Speakers say most of the Vunjo (central) dialects are intelligible with the Kibosho and Machame dialects of Hai (west). Hai and Rombo (east) are not inherently intelligible with each other (Polome 1980). 54% to 56% lexical similarity with Gweno, 41% to 44% with Taita. Value placed on children learning Chagga (Whiteley). SVO. Roman script. NT 1964.
